-tianA and State of Arkansas, have invented certain new and usefulImprovements in Building Construction, of which the following is aspecification.

My: 'present invention relates to certain new and useful improvements inlire-proof buildings, and it seeks to carry forward the system offire-proof construction, one type of which is disclosedin my Patent No.927,050, dated July 6, 1909.

My present invention has for its object to provide a re-proof wallconstruction wherein metallic partition studding serves to form theretaining and support-ing means for concrete, or other slabs without thenecessity of bolting or nailing the parts together, and the presentinvention includes means for spacing the parts of a double Wall apartto' form an air chamber within the wall.

This invention is a divisional part of my co-pending application filedOctober 25, 1909, Serial No. 524,495.

In its more subordinate nature the invention resides in those noveldetails of construction, combination and arrangement ofparts, all ofwhich will be first fully described, and then be specifically pointedout in the appended claims, reference .being had to the accompanyingdrawings, in which:

Figure 1, -is a diagrammatic view illustrat-ing the mannerofconstructing a double wall. Fig. 2, is an enlarged detail view of theform of metallic portion of the wall. Fig. 3, is a similar view of theform of studding used at the corners of a double wall.

Referring now to the accompanying drawings, inwhich like letters andnumerals of reference indicate like parts in all of the figures, andreferring particularly to Fig. 1, it will be seen that infthe straightrunning part of the wall the `Wall blocks 25E-4 Y are joined andsupported by a single interposed studding 10, formed of two sections,each of the same construction and together forming the single studding.Each studding section comprises a V-shaped spacing member 10HL mergingwith wing like body portions 10h-10" lying in' the same plane, from oneof which body portions 10", a series .of ears `right angles to lie studused in the straightv being bendable over right angles to that 10cproject, the ears 10c at 10d to Vlie in a plane at containing the bodyportions 10b. The opposite edge of each body portion 10b merges with astrip portion 10 that is bent parallel to the ears 10 when they are bentover, it being observed that the ears 10c of onehalf of the studding areadjacent to the uninterrupted bent over .ears 10e of the other half ofthe studding, or

vice versa. The two studding sections are` joined by rivets 1l that passthrough the body portions 10b and through spacing washers 11a, asindicated.

Where the-double walls studding is required, as best shown in Fig. 1ofthe drawings, by reference to which it will be seen that the cornerstudding 12 is formed of two sheet metal sections, each of `-which has aspacing member 12a merging with body Wings 1.2"512c that are bent inopposite'directions but lie inv diderent but parallel planes spacedapart a sufficient distance to give the required air spaces 2z betweenthe walls 2x-2Y. The body. portion 12c is of right angled form andis'provided with ears 12d that are bendable over to form a retainingmeans for one of the outer Walls 2X.

The other studding section is composed of a spacing member 12K-12fstudding sections are joined, forms in con` nection with the spacingmember 1,2, a parallelograrn having a long side l2s and short sides 12f.The short sides l2f join with the body portions'12g, one of which hasears 12h bendable over parallel to the side 12f to receive another' ofthe outer Wall sections 21?, while the other body portion 12. is of L-shape in cross section and has ears 12* that are bendable over andoutward to lie parallel with the projecting part 12x4 of the bodyportion 12b of the rst sect-ion to form a U- shaped channel to receiveone of the inner wall portions 2y, while the other wall portion `2y isreceived in the *channel formed by the body 12k and the adjacent side122 as shown. The two sides of the by rivets 13, that pass through thebody portions 12"-12k and 12C-42g and through spacing washers 121. V

By the use of my invention a simple, ,elfen-- tive and inexpensivedouble wall stadding'is'-- over at 2X-27 are joined at the corners, aslightly did'erent'form of )Patented Sept. i9, 1911i.. Divided and thisapplication iled tiebrnary which, when the studding 12 are joinedprovided that may readily serve its intended purposes and that willenable a strong wall to be built.

From the foregoing `description taken in connection with theaccompanying drawings it is thought the complete construction, operationand advantages of my invention will be readily lunderstood by-those'skilled in the art to which the invention appertains.

What claim is:

l. A corner partit-ion stud for .double walls comprising two sheet metalmembers and means for securing said members top gether, said sheet metalmembers having av central separating portlon bent to form aparallelogram in cross section, one of said sheet metal members havingportions bent into substantially U shape to form two parallel blockreceiving channels one at each side ofsaid central separating portion,said member also having al portion bent at right angles to saidchannels, the other member having a portion corresponding with said lastnamed member portion to form a U- shaped block receiving channel atright angies to the channels 'in said rst member,

said second member having a second ortion bent into substantiallyU-sliape to orm a second U-shaped channel also at right angles to theUshaped channels of said lirst member, substantially as shown anddescribed.

2. In a double wall construction, a metallic studding comprising a pairof sheet 'metal members each having a separating' portion, said sheetmetal members including a pair of parallelly .disposed block receivingchann nel portions, spacing members interposed between said sheet metalmembers, said sheet metal members being held back to back,

rivets passing through the sheet metal and spacing members to securethem together, said separating portions being bent to form a'parallelo-grain in cross sect-ion to make an acute angle with theadjacent block.

3. A metallic studding for double walls composed of two sheetmetalbodies having a pair of parallelly disposed block receiving channelportions at their sides, anda channeled separating portion between saidblock receiving portions, said bodies being held back to back anddefining a, quadruple grooved memberiiaving a central tubular portionforming a parallelogram in cross section.

4. A metallic studding for double walls
